The Anker SOLIX PS400 is the better panel if your station takes up to 60 V: you get 50 W more from a single fold-out panel and a clear IP67 rating. The BLUETTI PV350 is the safer match for stations with a lower voltage limit, because its 44 V open-circuit voltage leaves more margin than the PS400’s 57.6 V.
We pulled every figure from Anker’s and BLUETTI’s US product pages in November 2026. We haven’t unfolded either panel in the sun, so the comparison sticks to what each maker publishes.
Anker SOLIX PS400: more watts from one panel
Anker SOLIX PS400
- Rated power
- 400 W
- Open-circuit voltage
- 57.6 V
- Water rating
- IP67
- Weight
- 35.3 lb
Who it's for: Vehicle-based users who want 400 W from one panel and have a station with enough voltage headroom.
Strengths
- 400 W from a single panel
- Less setup than linking two panels
Weaknesses
- Heavy at 35.3 lb
- 57.6 V is close to a 60 V input limit
The PS400 is rated at 400 W, the most of any single panel we cover. Anker lists monocrystalline cells with up to 23% conversion efficiency, an operating voltage of 48 V, and 8.33 A of operating current. Its stand sets the panel at 30°, 40°, 50°, or 80°, which helps you aim it as the sun moves.
Its water rating is IP67, with one condition: Anker says to cover the MC4 ports with the rubber plug before rain or water. In the box, Anker lists two 9.8 ft MC4 solar charging cables, a 1.6 ft MC4 to XT-60 cable, and a safety manual.
The catches are voltage and bulk. Its 57.6 V open-circuit voltage sits close to a 60 V input limit, and Anker’s FAQ pairs it with stations that accept up to 60 V and have an MC4 input. It weighs 35.3 lb and opens to 100 x 39 in. Anker’s product page doesn’t list a warranty.
BLUETTI PV350: easier on your station’s input
BLUETTI PV350
- Rated power
- 350 W
- Open-circuit voltage
- 44 V
- Weight
- 32.4 lb
Who it's for: Owners of mid-size and large stations who want 350 W from one panel and have room to unfold it.
Strengths
- 350 W from a single panel
- Standard MC4 connectors
- Up to 23.4% conversion efficiency
Weaknesses
- Heavy at 32.4 lb
- 12-month warranty
- BLUETTI's page lists both IP65 and IP67
The PV350 makes 350 W with up to 23.4% conversion efficiency. Its open-circuit voltage is 44 V, with a Vmp of 37 V and an Imp of 9.5 A. That lower voltage gives more room under a station’s input ceiling. It uses standard MC4 connectors, and BLUETTI lists an operating range of -13 to 149°F.
Folded, it measures 29.3 x 30.9 x 2 in, a shorter fold than the PS400’s 39 in. It weighs 32.4 lb, and BLUETTI lists an ETFE coating and reinforced fiberglass.
There are two weak spots. The warranty is 12 months. The water rating is unclear: BLUETTI’s description says IP67, but its FAQ says IP65, so plan around the lower figure and keep it out of standing water.
How do the panels compare?
| SOLIX PS400 | PV350 | |
|---|---|---|
| Rated power | 400 W | 350 W |
| Conversion efficiency | Up to 23% | Up to 23.4% |
| Open-circuit voltage | 57.6 V | 44 V |
| Operating voltage | 48 V | 37 V (Vmp) |
| Operating current | 8.33 A | 9.5 A (Imp) |
| Water rating | IP67 | IP67 or IP65 (BLUETTI lists both) |
| Connectors | MC4 | MC4 |
| Folded size | 39 x 26.6 x 2 in | 29.3 x 30.9 x 2 in |
| Unfolded size | 100 x 39 x 1.2 in | 110.6 x 30.9 in |
| Weight | 35.3 lb | 32.4 lb |
| Warranty | Not listed | 12 months |
Which one gives more watts per pound?
The PS400 produces about 11.3 W per lb of panel and the PV350 about 10.8 W per lb, so the extra 2.9 lb of the Anker pays for itself in rated output. Real output depends on sun angle, heat, and cloud, so neither panel will hold its rated figure all day.
Voltage matters more than weight if you plan to link panels. Two PV350s in series would reach 88 V open-circuit, and two PS400s would reach 115.2 V. Both are past a 60 V input, so check your station’s limit before wiring panels in series.
How to choose
- Your station accepts up to 60 V on an MC4 input: the PS400 gives the most from one panel.
- Your station has a lower voltage limit: the PV350’s 44 V leaves more margin.
- Rain at camp: the PS400 has a clear IP67 rating; BLUETTI lists two different ratings for the PV350.
- A short trunk or a small storage spot: the PV350 folds to 29.3 in on its long side.
- You want a stated warranty: BLUETTI lists 12 months; Anker’s page doesn’t list one.
FAQ
Is the Anker SOLIX PS400 or the BLUETTI PV350 more powerful?
The Anker SOLIX PS400 is rated at 400 W and the BLUETTI PV350 at 350 W. The PV350 lists slightly higher conversion efficiency, up to 23.4% against up to 23%, but the PS400 has more panel area.
Will the Anker SOLIX PS400 work with my power station?
Anker’s FAQ says the PS400 works with stations that accept up to 60 V and have an MC4 input. Its open-circuit voltage is 57.6 V, so check that your station’s solar input limit is at least that high.
Can I wire two of these panels in series?
Check your station first. Two BLUETTI PV350 panels in series reach 88 V open-circuit, and two Anker SOLIX PS400 panels reach 115.2 V. Both totals are above a 60 V solar input, so a station with that limit can’t take either pair in series.
What cables come with the Anker SOLIX PS400?
Anker lists two 9.8 ft MC4 solar charging cables and a 1.6 ft MC4 to XT-60 cable in the box, plus a safety manual.
